Zygoma and Mandibular Angle Reduction: Contouring Surgery to Correct the Square Face in Asians

Changing the facial appearance with facial contouring surgery is popular, especially in East Asian countries where a square face is a common chief complaint. Mandibular angle reduction, malar reduction, genioplasty, and chin and body contouring surgery can be performed as independent or ancillary procedures during orthognathic surgery. Many techniques have been developed and different osteotomy designs have been proposed to enhance outcomes and minimize complication risks. Here, we review the surgical techniques and considerations for mandibular angle and malar reduction, the two most commonly performed contouring surgeries in East Asia to correct the square face.
